Your menstrual cycle is a window into your overall health. Understanding what's normal — and what's not — can help you seek timely care and maintain reproductive wellbeing.

A typical cycle lasts between 21 to 35 days, with bleeding lasting 2 to 7 days. The amount of blood lost is usually 20–80 ml. Cycles can vary month to month, but significant changes in frequency, duration, or volume may need medical attention.
Heavy bleeding (soaking a pad/tampon every hour), periods lasting more than 7 days, cycles shorter than 21 days or longer than 35 days, severe cramping that interferes with daily life, and bleeding between periods are all signs you should consult a gynecologist.
Estrogen and progesterone regulate your cycle in phases — the follicular phase, ovulation, the luteal phase, and menstruation. Imbalances in these hormones can cause PCOS, endometriosis, thyroid disorders, or other conditions that affect cycle regularity.
If you experience missed periods for more than 3 months (and aren't pregnant), extremely painful periods, or any sudden changes in your cycle pattern, schedule a consultation. Early evaluation leads to better outcomes.
Dr. Nasreen's Tip
Track your cycle using a simple calendar or app for at least 3 months. Bring this record to your consultation — it gives your doctor valuable diagnostic information.
